Europe's extreme heat: operational impacts and resilience considerations

Extreme heat is disrupting Europe. Learn key operational impacts and resilience steps, including continuity planning and parametric insurance options.

Extreme heat is affecting Europe this summer, with temperatures reaching 41 C in parts of Germany, France, and Eastern Europe. The European Centre for Medium-Range Weather Forecasts (ECMWF) has described Europe as the fastest-warming continent, and the current event is another reminder of how extreme heat translates into operational disruptions.

What are the impacts

The effects of extreme heat extend beyond discomfort. Rail and road networks are under pressure; low river levels can affect logistics and industrial cooling; and outdoor work is becoming more difficult to manage safely. Warm nights also reduce recovery time for people, assets, and infrastructure.

These impacts are particularly relevant for organisations with temperature-sensitive supply chains, labour-intensive operations, or heavy dependence on cooling systems. In these environments, extreme heat can drive lower productivity, higher operating costs, and a greater likelihood of interruption.

Why it matters

Transport disruptions can affect both passengers and freight, particularly when rail and road networks operate under extreme heat-related restrictions.
Worker safety protocols may need to be adjusted when prolonged exposure to extreme heat raises health and productivity risks.
Energy demand can rise at the same time that cooling systems are under greater strain, increasing the risk of service disruption.
Cold chains and food systems are more exposed when storage, transit, or handling conditions become harder to control.
Repeated extreme heat exposure can turn a short-term weather event into a broader business continuity issue.

How organisations should respond

If your organisation is seeking to build greater resilience to extreme heat-related events, you should ask the following questions before taking action:

Which of our sites, suppliers, and processes are most exposed to prolonged extreme heat conditions?
Do our continuity plans address scenarios involving several consecutive days of extreme heat?
Are our workforce controls, including rest breaks, hydration, and scheduling changes, appropriate for current conditions?
Have our dependencies on power, water, transport, and cooling been tested under extreme heat stress?
Do our insurance and risk transfer arrangements address business interruption and additional expense linked to extreme heat-related disruption?

Your organisation should also consider whether potential losses can be tied to a measurable extreme heat temperature threshold. If so, parametric structures that complement traditional insurance may be worth exploring as they often can provide liquidity sooner. Their suitability for your organisation will depend on the quality of the trigger design and the degree of basis risk.

Outlook for the future

Extreme heat is likely to remain a recurring feature of European summers, turning it into an ongoing business risk rather than a one-off weather event. Organisations that identify their exposures, assess their insurance coverage and risk transfer options, and test continuity and response plans now will be better placed to protect their people, operations, and financial performance during future periods of extreme heat.

Marsh can work with your organisation to improve its overall climate resilience. Our Alternative Risk Solutions team, in particular, can assist you with evaluating your parametric options.
